Matte surface film

A skin layer of a thermoplastic polymer includes an additive to promote metal adhesion to the surface of this layer. This additive is one or more compounds of the formula, R-X, where R is an aliphatic hydrocarbyl group having an average of from 20 to 200 carbon atoms and X is a polar group, such as &mdash;COOH or &mdash;CH OH. The film may be biaxially oriented and include a polypropylene core layer. The film may be metallized with an appropriate metal, such as aluminum. A heat sealable skin layer may be provided on the opposite side of the film from the metallizable skin layer.

Film with metallizable skin layer

A film structure comprises a first sealable skin layer (a) of an olefin co- or terpolymer having an external surface which contains a slip/antiblock system. The slip/antiblock system comprises non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane and silica antiblock particles. Layer (a) is located on one side of a core olefinic polymer layer (b). On an opposite side of the core layer (b) there is a second skin layer (c) which is ethylene homopolymer and which is free of the slip/antiblock system, optionally the second skin layer (c) is metallized.

Film structure

A film structure comprises a first outer skin layer (a) of an olefin co- or terpolymer having an external surface which is sealable and machinable, the first skin layer containing a non-migratory particulate crosslinked hydrocarbyl substituted polysiloxane, and which is located on one side of a core olefinic polymer layer (b) on an opposite side of the core layer there is a second skin layer (c) which is ethylene homopolymer and which is free of the particulate crosslinked hydrocarbyl-substituted polysiloxane of the first skin layer, the second skin layer. In one embodiment, for improved barrier properties, the ratio of particle size to thickness of the (a) skin layer ranges from about 1.25 to about 2.5.
